Class XmlPullParserFactory

java.lang.Object

org.xmlpull.v1.XmlPullParserFactory

public class XmlPullParserFactory
extends Object

This class is used to create implementations of XML Pull Parser defined in XMPULL V1 API. The name of actual facotry class will be determied based on several parameters. It works similar to JAXP but tailored to work in J2ME environments (no access to system properties or file system) so name of parser class factory to use and its class used for loading (no classloader - on J2ME no access to context class loaders) must be passed explicitly. If no name of parser factory was passed (or is null) it will try to find name by searching in CLASSPATH for META-INF/services/org.xmlpull.v1.XmlPullParserFactory resource that should contain a comma separated list of class names of factories or parsers to try (in order from left to the right). If none found, it will throw an exception.

NOTE:In J2SE or J2EE environments, you may want to use newInstance(property, classLoaderCtx) where first argument is System.getProperty(XmlPullParserFactory.PROPERTY_NAME) and second is Thread.getContextClassLoader().getClass() .

Constructor Detail

XmlPullParserFactory

protected XmlPullParserFactory()

Protected constructor to be called by factory implementations.

Method Detail

setFeature

public void setFeature(String name,
                       boolean state)
                throws XmlPullParserException

Set the features to be set when XML Pull Parser is created by this factory.

NOTE: factory features are not used for XML Serializer.

Parameters:

name - string with URI identifying feature

state - if true feature will be set; if false will be ignored

Throws:

XmlPullParserException

getFeature

public boolean getFeature(String name)

Return the current value of the feature with given name.

NOTE: factory features are not used for XML Serializer.

Parameters:

name - The name of feature to be retrieved.

Returns:

The value of named feature. Unknown features are always returned as false

setNamespaceAware

public void setNamespaceAware(boolean awareness)

Specifies that the parser produced by this factory will provide support for XML namespaces. By default the value of this is set to false.

Parameters:

awareness - true if the parser produced by this code will provide support for XML namespaces; false otherwise.

isNamespaceAware

public boolean isNamespaceAware()

Indicates whether or not the factory is configured to produce parsers which are namespace aware (it simply set feature XmlPullParser.FEATURE_PROCESS_NAMESPACES to true or false).

Returns:

true if the factory is configured to produce parsers which are namespace aware; false otherwise.

setValidating

public void setValidating(boolean validating)

Specifies that the parser produced by this factory will be validating (it simply set feature XmlPullParser.FEATURE_VALIDATION to true or false). By default the value of this is set to false.

Parameters:

validating - - if true the parsers created by this factory must be validating.

isValidating

public boolean isValidating()

Indicates whether or not the factory is configured to produce parsers which validate the XML content during parse.

Returns:

true if the factory is configured to produce parsers which validate the XML content during parse; false otherwise.

newPullParser

public XmlPullParser newPullParser()
                            throws XmlPullParserException

Creates a new instance of a XML Pull Parser using the currently configured factory features.

Returns:

A new instance of a XML Pull Parser.

Throws:

XmlPullParserException - if a parser cannot be created which satisfies the requested configuration.

newSerializer

public XmlSerializer newSerializer()
                            throws XmlPullParserException

Creates a new instance of a XML Serializer.

NOTE: factory features are not used for XML Serializer.

Returns:

A new instance of a XML Serializer.

Throws:

XmlPullParserException - if a parser cannot be created which satisfies the requested configuration.

newInstance

public static XmlPullParserFactory newInstance()
                                        throws XmlPullParserException

Create a new instance of a PullParserFactory that can be used to create XML pull parsers (see class description for more details).

Returns:

a new instance of a PullParserFactory, as returned by newInstance (null, null);

Throws:

XmlPullParserException

newInstance

public static XmlPullParserFactory newInstance(String classNames,
                                               Class context)
                                        throws XmlPullParserException

Throws:

XmlPullParserException
